Aaron Tartakovsky
Aaron Tartakovsky is turning the least glamorous room in a building into a small piece of urban infrastructure - and using beer to persuade the rest of us to look.
Prakash Govindan
Prakash Govindan is the co-founder and CEO of Gradiant, the water industry's first unicorn, valued above $1 billion. Raised in Chennai during monsoon failures that dried up his family's taps, he turned a childhood of hauling buckets into a PhD at MIT and a company that now renews billions of liters of industrial water a day for clients in semiconductors, pharma, food and beverage, and mining. He co-invented Gradiant's flagship Carrier Gas Extraction technology, holds more than 100 patents, and helped bring the TIME Best Invention 'ForeverGone' PFAS-destruction system to market. A devoted bhakti yogi who has read the Bhagavad Gita some fifty times, he runs one of the fastest-growing water companies on earth while preaching egoless leadership.
Nicholas Dyner
Nicholas Dyner is the CEO of Moleaer Inc., the Hawthorne, California company that turned nanobubbles - gas bubbles 2,500 times smaller than a grain of salt - into an industrial-scale tool for growing more food, cleaning more water, and reviving dying lakes. A Cornell history-and-economics major who fell into the water industry through a GE leadership program and never left, Dyner has spent nearly two decades selling water-treatment technology in more than 90 countries. Since 2017 he has guided Moleaer from a wastewater experiment to over 10,000 installations across 55 countries, a partnership with Xylem, and a multi-billion-dollar category that barely existed before he showed up.
